"The Brothel" is a confusing film, a taste of which we get in the very first scene. I had trouble choosing a rating for the film, just as I had trouble sticking it out to watch through the whole length of it. I'm glad that I did stick it out in the end, even though I find the overall work only mildly satisfying.
Approach "The Brothel" in expectation of beautiful period costumes and sets, characters who are intriguing even if perhaps needlessly opaque for much of the film, yes some beautiful bodies (of both genders) and a bit of sex. Ultimately the film reaches a resolution which does make some sense and does provide a sense of closure to the viewer and for the characters. Suspend your disbelief while on the ride. Enjoy its individual pieces as it passes over and maybe a little bit through you.
Many viewers will feel that the payoff is insufficient to the cost of viewing through the whole film. I'm - just barely - not one of them, and did enjoy the film, having reached the end. If you turn this film off in the middle, then your time will have been wasted. If you reach the end, then I hope that you will be satisfied, just enough, as I was.
